Aball is thrown with initial speed v0 up an inclined plane. the plane is inclined at an angle φ above the horizontal, and the ball’s initial velocity is at an angle θ above the plane. choose axes with x measured up the slope and y normal to the slope. you can neglect the z coordinate as the ball remains in the xy-plane (z = 0).
(a) write down newton’s second law using these axes and find the ball’s position as a function of time. (your solution only needs to be valid for times before the ball lands back on the inclined plane.)
(b) show that the ball lands on the plane a distance r = 2v0 2 sinθ cos(θ + φ) / (gcos2 φ) from its launch point.
(c) show that for given values of v0 and φ, the maximum possible range up the inclined plane is rmax = v0 2 /[g(1+ sinφ)].

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
